Australia is a major exporter of liquefied natural gas (LNG), with considerable potential for further development based on its abundant resources of natural gas. Australia is the third largest LNG exporter in the Asia-Pacific region and the fourth largest LNG exporter in the world, exporting 17.9 million tonnes in 2009-10 with a value of around $7.8 billion. The LNG industry is attracting significant new project investment providing major benefits in the form of long-term employment, economic benefits and government revenue.
The Department plays a pivotal role in the development of Australia's LNG industry primarily through its role in regulating offshore petroleum development. As the LNG market has matured, the Department's primary focus is on ensuring that LNG development proposals are: consistent with good oilfield practice; safe; meet stringent environmental standards; benefit the Australian economy and community; and that regulatory approvals are carried out in an efficient and consistent manner.
What is LNG?
LNG is natural gas, primarily methane, which has been cooled to minus 161°C to reach its liquid state. Liquefying natural gas reduces the volume it occupies by more than 600 times, making it a practical size for storage and transportation in specifically designed and built tankers. LNG is widely recognised as a clean, safe and convenient form of energy, which can be readily supplied to distant markets. It is transported to dedicated LNG receiving terminals, which have the capacity to store and re-gasify the LNG for supply to markets. LNG, in its liquid state, is not flammable or explosive.
Australia's Natural gas resources
Methane gas feedstock for LNG production can be sourced from either conventional natural gas fields or from coal seam gas (CSG) associated with coal deposits. Abundant conventional natural gas resources have been identified offshore of North and Western Australia in the:
- North West Shelf Project area;
- Gorgon Project fields;
- Browse Project fields;
- Bayu-Undan fields;
- Greater Sunrise Project fields;
- Scarborough fields; and
- more recently, the Pluto, Wheatstone, Ichthys and Prelude fields.
In Eastern Australia, large CSG resources have been discovered onshore in Queensland and to a lesser extent in New South Wales.
Australia's LNG plants
Currently, there are two operating LNG processing plants in Australia, the North West Shelf (NWS) LNG Project in Western Australia and the Darwin LNG plant. The NWS Project has five LNG production trains with a total production capacity of 16.3 million tonnes per annum (mtpa) and the Darwin LNG plant's single production train has a capacity of 3.6 mtpa.
There are several other Australian LNG projects at various stages of development with the 4.3 mtpa Pluto LNG plant being the most advanced and due for startup in 2011. The massive Gorgon LNG Project (initial 3-train, 15 mtpa production capacity) is also under construction and is due for startup in 2014-2015.
Other well-advanced LNG projects that are yet to receive a final investment decision are the Wheatstone, Ichthys and Browse LNG projects. Floating LNG, the production of LNG via a large, barge-like floating LNG production facility, is also under consideration to develop the Prelude field and other smaller offshore gas fields that are distant from either land or existing infrastructure.
As yet, there are no operational CSG-LNG projects in the world. However, the Queensland Curtis LNG and Gladstone LNG projects are currently under construction in Gladstone, Queensland. There are also several other proposals for CSG-LNG plants under consideration for Gladstone.
Australia' LNG exports
Australia has sales contracts in place to supply LNG to Japan, China, South Korea and India and has made spot market sales to numerous other countries. During 2009, the vast majority (66%) of Australia's LNG exports were to Japan as shown in Table 1 below.

Australia-China Natural Gas Technology Partnership Fund
At the time the North West Shelf (Australia) - Guangdong (China) LNG sales agreement was struck, the Australian Government, the Government of Western Australia and the partners in the North West Shelf Venture agreed to establish the Australia-China Natural Gas Technology Partnership Fund that provides opportunities for training, research and knowledge transfer between the people of China and Australia in the natural gas and LNG industries.
